TAG-1VIOUNTING MACHINE.

Application filed March 4, 1922. `Serial No. 540,956.

To all whom it may concern:

Be it known that I,-Mo1nus G. `RosnN'ri-IAL, `aicitizen of the United States, and a'residenty of Cincinnati, in the county of I-Iamilton and State of Ohio, have invented certain lnew and useful Improvements in Tag- Mounting Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of vthis specification.

My invention relates 'in its special Aapplication to devices for stitching tags to articles of laundry for the purpose of identifying them, said tags to be sewed on with a stitch that will pull out, so as to permit removal of the tag.

The development of this machine has as its objects various features, some of which have application to sewing machines in general, and some to tag feeding devices and the like.

Thus it is my object to provide a stop motion for sewing machines, which operates to stop the operation of the machine by first shutting offV the motive power and then permitting the parts to run of their own momentum for certain revolutions or parts of revolutions, after which they are positively stopped.

It -is my object t-oprovide a mechanism which will control the number 4of stitches made bythe needle, `which by the substitution of different toothed pinions and cams, can give any desired number of stitches prior to the stop and any ydesired momentum revolutions.

It is my object to provide in connection with the machine a thread cutter which will be of positive operation and will give a length of thread free for ready accessibility in pulling out the stitches. i

It is also my object to provide a feed device for rigid or semi-rigid individual tags, which will feed a tag into the stitching p irts of the vmachineand then release it sufficiently to permit the `fabric-feed ofthe machine to draw it along with the fabric towhich vthe tag is being stitched.

The holderfor marking tags is especially designed to receive the metal `and fabric hanger tags, of the type 'shown in my ap- Serial No. 526,171. y

In connection with the. timed stop motion "device, it 1s my obiect to provide for al simple and effective resilient bumper action, secure against back `lash and capable of locating the fly wheel and shafting of the machine so that the needle is always elevated when vthe machine is stopped.

Ihave not attempted to modify the action of the sewing machine proper and have not shown in detail the kind of machine used, since any'draw thread machine would be proper for use. In the broader aspects of my invention, either lock or chain stitch machines coul-d be used, the reason for using a draw thread in the tag mounting machine being because I desire to permitremoval of the tag by pulling out the thread or threads of the stitches.

The above objects and other advantages to be noted I accomplish by that certain construction and arrangement of-parts tofbe `hereinafter more specifically pointed out and claimed.

AIn the drawings,

Figure 1 is a front elevation ofthe machine complete except for the starting pedal.

Figure 2 is a detail side elevation of the. timing members of the stop motion.

Figure 3 is a detail end `elevation with certain parts removed, showing the machine shaft stopping elements. e

Figure t is a detail end elevation showing the connectionsbetween the starting pedal and the presser foot arm. v

Figure 5 1s a detail plan view showing the vpresser foot, tagA holder` and tag feed, with in the drawings showing any familiar tric motor (not shown). vI have dia-grammatieally shown a foot pedal 6 connected to al pull rod 7 and having also thereon a bar 3, which operates a switch enclosed in a cabinet 9.

`Pivoted to the frame of the machine a rocking bar 10, its pivot being on a stud 11. Iuthis bar is slidably held a spring bumper post 12. On a pin 13, extending from the top of the rocking bar a frame 11i is journaled. This frame is constructed substantially7 as shown in Figures 1 and 3, with the back portionextended to form a latch 1e' with a beveled engagement face 1G. A torsion spring' 17, bearing against the upper portion of the frame is wound around the pin 13, with one end retained by the rocking bar. rl`he other end is attached to the frame so that the frame is resiliently held by the spring in :a horizontal rotative position against a bar 18 extended from the rocking arm.l This bar engages the rtop partof the pin 13 and a tension spring v19 with one end abutting the bar 18 and the other abutting the frame which presses downwardly against the small frame.

On the shaft 5a is an arm 2O having a beveled end, which, as the shaft revolves, will first strike the beveled face 1G of the hook latch 15` so as to swing the frame out of the way. The arm 2O will then strike the spring bumper post and be brought toy a stop, while as soon as theY post is struck by the arm, the frame will be permitted to swing` to its original position, bringing the hook over the arm and thereby providing a resilient take-up for any rebound and holding the shaft arm at a predetermined position, which, as stated, will leave the Vneedle elevated, ready for another operation.

The bar 10 has two teeth on its lower end, the tooth 21 and the tooth 22. The former tooth is engaged by a` pawl 23 pivoted at 24 on the machine frame, and connected to the pull rod 7 of the foot pedal 6. The toothr 22 is adapted to be engaged by the shoulder 25 on a rocker arm 26 pivoted at 27 on the machine frame. The bar 10 is pulled bya spring 27a toward a position with the latch 15 and the bumper post 1.2 in alignment with the arm on the machine shaft. lVhen in such position, the tooth 21 at the lower end of the bar contacts with another shoulder 28 on the rocker 26. The pawl 23 is spring pulled at i8a to a position ready for engagement with the toot-h 21 of the bar.

As so constructed, the operation of pressing down on the pedal rocks the pawl 23 and moves the lower end' of the bar 10 so as to swing the latch and bumper post out ot position to block the operation of the machine. lThe tooth 21 which engages the pawl as long as the bar 10 is in an approximate vertical position disengages the driving edge of the pawl at the point of. extreme throw of the pawl as moved bythe foot pedal 6. To hold the' rocker 10 in position when the pawl is no longer in cooperative position with the tooth 21, the tooth 22 strikes against the shoulder 25 ou the rocker bar and'thus holds the arm 10 in this position. The shoulder 25 holds the arm 1() in position until the machine shaft causes the rocker arm to be rocked up at the end opposite the shoulder so that the shoulder disengages the tooth and the arm 1() is pulled by the spring 27 back to the verti- "al engaging position. The footy pedal as soon as it is released is pulled up by a spring` which will be hereinafter described and the pawl moves back to the starting position with its edge in position to engage the tooth 21.

Upon a movement of the roel\:er,th`e bar 1()A will be freed to move under impulse of itsspring into shaft blocking position,"and the pawl 23 will be free of the bar and its teeth until the rheostat'switch is released, when the pawl will come into engagement with the tooth 21, ready to operate the bar for another operation of the machine.

The pedal will either have its own spring or will be pulled by the spring on the pawl 23 into elevated position when it is released, thereby turning oit' the current` from the `drivingmotorthrough themedium of the switch. The pedal will have to be held down throughout the major part of the' motion of the machine. y

I also provide for an additional switch for the current to the motor, which is controlled from a timing device rconnected to the moving parts of the sewing machine.

Thus I show as an exemplary form, a terminal 30, to which is connected a resilient metal conductor strip 31. The other end of this strip is connected to a link 32, which is pivoted to the rocker 26 and a slight movement of the rocker not suticient to release the stop bar 10, ywill move thc strip 31, so that itdoes not maintain a contact with 'the other electric terminal 32a. By this means, a partial movement' of the rocker will cut oit the flow of current to the motor and 'the machine parts are still free to fly around of their own momentum until a'further movement is applied to* the rocker to entirely release the bar 10. n Y

On a shaft 33, which operatesthe lower thread parts of the sewing machine and the work feed and which is connected to 'the main shaft by suitable means, is a collar 34* Located above this `collaris a star wheel or `gages, so thatat eac-h revolution of the shaft 33, which is timed to be equal to the cycles of movement of the needle, the star wheel is given a movement of one tooth.

On the star wheel is a Cam 37 Aagainst which rests the rod 38 connected to the rocker 26. A spring 39l around the rod holds the rocker in position with 'the .rod

thereon against the cam, and incidentally' the shouldered outer end in position to sli-ring into engagement with the bar 10 and` also the switch plate in position to maintain an electric contact.

The cam has its periphery arranged with a surface zl0,which will hold the rocker in position to pull the switch strip out of contact, and a high nose 41 which will release the rocker from engagement wit-h the bar 10.

I preferably arrange the parts so that the portion l() of the cam will hold the switch ont for about two revolutions of the ily wheel and main shaft, after the current has been sluit off.

The advantages of this form of stop motion are obvious, as they free the motor and the parts of the sewing machine from jar incident upon stopping the mechanism.V

The presser foot 39a ,of the'machine is connected by a rocker arm L with a link Ll1`. This link 41 is attached to'a lever 42 which is coupled to the pull rod ofthe foot pedal, and a spring 43 attached between. the frame and-the lever exerts a` tension to pull down on the link 41 and raise the presser foot so that the work will be free to move under theneedle, as in any sewing machine. lilhen the foot pedal is depressed to start the motor and release the main shaft of the machine, the presser foot will be released, so that the work will' be clamped down beneath the foot. lVhen the machine stops and the. lever 4t2 is not interfered with, the spring l-lpulls the lever so as to raise the presser foot, overcoming the forte of the normal spring of the presser foot.

T he tag holder is constructed as follows: A three-sided rectangular box la is provided of the cross section equal approximately lo the size of a tag. In this box are a .pair of pins t5 having their upper and lower ends pointed as at d6. The tags, as shown, have body portions` el? in which are holes L18 having narrow slits -l-t extending from the holes to the backs of the tags. The fronts of the tags may be made up of a flexible loop of fabric 50. 'T he slits in the backs of the holes will slide over the pointed ends of the pins,`

but the act of moving the tags along the pins from the ends will result in the large parts of the pins filling the holes and retaining the tag slidably but irremovably.

il. small platform 51 is erected on the the needle, this platform having an `overhanging `lip or tongue 52 and a short stud 53. The box 114 is formed with flanges at its lower end, one of which, as at 54, is adapted to be inserted under the tongue 'and the `other of which, as at 55, has a hole therein vto'engage"over the stud. A latch 56, mounted alongside the platform, swings over this flange 55, thereby holding the box down firmly with the stud acting as a locating member. i

Hung on a suspended link 57 is a tongue 58 which, when the link is swung, will pass through a slot 59 in the back wall of the boxY at the` base thereof.

The box, when seated on the platform, acts to push the two pins into a position so that the pointed ends are within the inside of the box, so that the lower-'most tag can slip out of the open front of the box.

link is swung so as to insert the tengue through its slot and push the lowermost tag forward to a position beneath the presser foot.

In mounting the tags in the box it is removed from the platform, whereupon the two `pins will fall until the pointed ones al tl' top are within the box, whereupon `the boia 'can be filled with tags inserted from above and dropped down over the pins.

To serve as a lateral guide in the feeding vof thetags, the platform is formed with a shoulder GO from which extends a pin 60, which lies above the platform, said plat'fo'rnji having a slight slope at this point. On the other side of the platformis a rockingarn'i G1 mounted on a stud and bracket 62 and having a spring-pressed end Gt, the other` side of the stu'd. A linger 6ft extends inwardly from the presser foot and engages the spring-pressed end of the arm, so that when the presse-r foot is raised, as it is when the tags are fed, the arm lies along the platform and forms the other side guide. lli/'hen the machine is working and the foot is down, thelinger 611 will raise the arm, thereliiy pei'- mitting the tag to feed along with the fabric to which it is being stitched.

Starting with the presser foot up and the machine idle, the operator inserts a piece of fabric to be marked beneath the presser foot and un-der the needle. He then throws over the arm 57, which forces a tag out of the box, since the pins in the box will have been thrust upwardly in mounting lthe box, there by bringing the thin ends of the two tag retaining pins up into the box and freeing the lowern'iost ta for sliding outivardly.

The tag moves to a position lying directly beneath the needle over the fabric to be marked, the tongue 5S having a limited movement detern'iined by the link 5l`striking the box or any other stop desired.

The loperator then presses down on the foot work table of 'the ,machine to the right of pedal which pulls over the stopdevice to -free the main shaft of the machine, and at the same time electrically connects in the motor through the box 9 (preferably a rheo-` stat switch). Y

` lVhen the arm l0 is swung over the rocker Q6 is free to move under influence of the spring 39, thereby keeping the circuit to the motor at 32 closed. ofthe pedal the presser foot comes down, clamping the fabric 'end ofthe tag to the fabric, and the machine starts to stitch the tag to the fabric with a chain stitch.

'ihe presser foot has freed the tag so that it can move along with the fabric under influenceof the usual work feed in the machine by rocking down the rear end 63 `of the guide member (il.

rlhe needle will move up and down for the desired number of motions, say, four, whereupon the devices beneath the table coupled up with the lower needle shaft will make the first movement that cuts'oft the current at Bj without releasing the arm 10 with the catch and bumper post in position to block the arm 2O on the needle driving shaft. rThe motor and sewing machine parts wili continue to move because of the kinetic energy remaining` in them, for say, two more motions of the needle, vwhereupon the rocker `26 willcomplctc its movement, thereby. releas-.'

ing the stop device and bringing the machine operating parts to a full stop,with the needle elevated. `Upon thel release ofthe foot pedal as noted the the elevated position.

rIhe operator then withdraws the fabric and tag, and cuts ofi" the thread, by means of a special mechanism which I will now describe.'

This mechanism comprises a knife mounted in a slot in the table l of the machine. A guard 7l is provided which is screwed down to the table over the slot as illustrated at 72, and has a slot 73 therein lying over the knife. Due to a slight inclination in the guard, the knife lies vin the slot for a partrof its length, but the knife is turned down at 74, and lthe guard turned up at 75, permitting the easy introduction of `thethreadbetweeuknife and guard bythe operator.

As the operator pulls the fabric and tag to bring the thread under the guard and caught between the guard and knife and pressed against the knife by the guard, so that it is easily sheared as it is pulled along the knife edge. f

The machine is then ready for another operation with the parts` all at rest and everything` reset for another operation. The spring 57 pulls back the feed tongue, as will be evident, andthe return of all other parts has already been noted. u
